PROBLEM TO BE SOLVED: To provide a switch device capable of transferring a plurality of low-delay frames addressed to the same output port while avoiding collision of the low-delay frames.SOLUTION: The switch device comprises a plurality of ports. The switch device includes: a P1 output delay adjustment part 41, a P2 output delay adjustment part 42, a P3 output delay adjustment part 43 and a P4 output delay adjustment part 44 by which, if the collision is detected regarding the plurality of low-delay frames which are inputted to the other ports and outputted from one port, priorities of the plurality of low-delay frames are determined and delay adjustment amounts of the plurality of low-delay frames are calculated on the basis of the priorities; and a P1 variable delay part 61, a P2 variable delay part 62, a P3 variable delay part 63 and a P4 variable delay part 64 by which the low-delay frame inputted to the one port is delayed with the delay adjustment amounts which are calculated by the P1 output delay adjustment part 41, the P2 output delay adjustment part 42, the P3 output delay adjustment part 43 and the P4 output delay adjustment part 44 of the other ports.SELECTED DRAWING: Figure 1 |
